2000 Chrysler Concorde Alternator Problem

Tony’s question:

glad to know you’re still around. Have a 2000 chrysler concorde and replaced battery and told that alternator needed to be replaced but then someone else told us that the voltage regulator in this make and model is not in the alternator. What do you suggest? You have been a great help to us in the past and I have saved hundreds of dollars following your advice. So thanks in advance


To be absolutely sure where the regulator is, get your VIN number out and contact a Chrysler dealer. They can tell you if the alternator has the regulator built in or not. BUT, on many of those Chryslers, the main computer of the car actually regulates the charging of the alternator. Of course, you must realize that the alternator itself could be bad in and of itself, regardless of where the regulator is located. Any good mechanic or auto parts store can run a test on the alternator to tell you if it’s bad or not. Just realize that in those Chryslers with regulators built into the computer, that if the alternator burns itself out, many times it will also burn out the regulator section of the main computer and require replacing the expensive main computer also. Hey, I don’t design these things, I just fix them. If I designed them, they would be quite a bit different than they are today.

1998 Chrysler Concorde State Emission Test Fail

Alberto’s Question: My 98 Concorde failed the state emissions test last week. It had the code for misfire on cylinder # 5. I changed out the spark plugs, the wires, and even the fuel injector on number five. Still won’t pass the test with the same misfire code. What am I missing?

Answer: Well, you covered the common problems for misfires on one cylinder. But of course, there can be many other causes–like a bad main computer, bad wiring, bad valve springs, or even a crack in the engine head. BUT, I was once bitten by a Concorde with the same problem as yours. I eventually fixed the car by replacing the intake manifold gasket. There was a TINY crack on the intake runner for the number five cylinder. I could only see it when I removed the intake manifold. There was carbon black around the crack where it had been leaking. SO, you might find someone with a smoke machine and see if they can smoke out a leak in the intake system. Since it’s misfiring on number five, pay close attention to the manifold gasket around number five.
